Public reports show that crimes linked to Smartphones have increased sharply in past years. Because of the largest market share of Android, forensics on Android device had become a focus in the field of digital forensics. Data acquisition is a key aspect for smartphones forensics. In this paper, we proposed an improved approach of acquiring data image using special modes of Qualcomm processors, which almost taken more than half of market share of mobile smartphones' CPU. Evaluation experiments confirmed that proposed methods are practicability and the data integrity of extracted partition images is preserved. This work is intended to provide vital references for the investigators and researchers working on the digital forensics.
